There is a way to provide a VFP solution for a Pocket PC, I've being doing these for several months. as Sergey have said, you can't run a VFP aplication in Pocket PC, however there is a tool we've being using for warehouse inventory with wireless technology, we use some symbol pdt8100 with pocket pc 2002

the tools is called Wavelink, you can visit the site www.wavelink.com, you won't be able to get enough info there, but wavelink is just a set of object you can use to build kind of DOS screen that runs in a serer and are seen at the handhelds using a wavelink client.

the programing is quite similar to what we used to do with FPDOS, sequential, but you have almost all the capabilities of VFP, meaning objects, API's, and so on.

There is an article at foxproadvisor named "Go wireless with VFP and Wavelink" that is kind of a walkthrough to use these tools together. the article is quite simple but covers the first step to program with that.

personally I don't think wavelink is a tool for a big company, however could be relly good for small bussness solutions.
